  • Patent number: 10370779
    Abstract: A method is provided for operating an air spinning machine with a multiple number of spinning units, whereas each spinning unit has a spinning nozzle with an internal vortex chamber. The spinning nozzle is fed a fiber composite during the operation of the spinning unit. The spinning nozzle has a multiple number of air nozzles leading into the vortex chamber through which compressed air streams into the vortex chamber in order to generate a vortex air flow within the vortex chamber. The fiber composite receives a twist with the assistance of the vortex air flow within the vortex chamber such that a yarn is formed from the fiber composite. The air spinning machine features an additive supply, whereby an additive is at least temporarily fed a part of the spinning units. A liquid additive is used, whereas the additive is degassed prior to leaving the additive supply. In addition, an air spinning machine with a degassing device is described.

  • Patent number: 10074463
    Abstract: A method for making a high-temperature winding cable is winding a tinned copper line around a coaxial line, signal lines and power lines after being assembled together, lapping the rim of the tinned copper line with a packaging material of Polytetrafluoroethene, and then, extruding an insulating layer of thermoplastic material on the rim of the packaging material, and finally, extruding an outer cover of fluororubber on the outer rim of the insulating layer, thereby forming a cable; sintering the cable; winding the sintered cable clockwise around and fixing it to a iron bar; cooling the wound cable; and finally, taking down the wound cable from the iron bar by rewinding it counterclockwise so as to obtain a high-temperature winding cable. The winding cable so made is not melt, damaged, and retains elasticity after the impact of high temperature 260° C.

At least some embodiments employ a disk of piezoelectric material with low planar coupling and low Poisson's ratio mounted on a backing material and sealed inside an enclosure. The piezoelectric material disk has a pattern of electrodes deposited on an otherwise smooth, ungrooved surface. Despite the lack of grooves, the material's low planar coupling and low Poisson's ratio enables the electrodes to operate in a phased relationship to provide and receive focused acoustic pulses. Moreover, the elimination of deep cuts offers a much lower cost of construction. The electrode material may be any conductive material, though silver and silver alloys are contemplated. The patterning of electrodes can occur during the deposition process (e.g., using a silk-screen or other printing technique) or afterwards (e.g., mechanically or chemically with an etch technique that uses a pre- or post-deposition photoresist layer).

  • Patent number: 7469470
    Abstract: A cable comprises at least two cores stranded together, an expanded inner jacket layer, a substantially circular metallic armor partially contacting the inner jacket to form unfilled interstices outside the inner jacket, and a polymeric outer jacket. The expanded inner jacket substantially takes the shape of the periphery of the stranded cores, providing a non-circular cross section for the expanded inner jacket. A method of producing a cable comprises providing at least two cores, expanding a polymeric material, extruding the expanded polymeric material around the cores, and allowing the expanded polymeric material to collapse onto the cores. A substantially circular metallic armor is applied, resulting in a plurality of unfilled voids between the inner jacket and the metallic armor. An outer jacket is extruded on the metallic armor.

  • Publication number: 20080178983
    Abstract: A composite-forming process includes impregnating a reinforcing structure with a curable composition at a temperature of about 10 to about 40° C. The curable composition includes specific amounts of an epoxy resin, a poly(arylene ether), a solvent, and a curing promoter. The poly(arylene ether) includes, on average, about 1.6 to about 2.4 phenolic hydroxy groups per molecule, and it has a polydispersity index less than or equal to 2.2 and an intrinsic viscosity of about 0.03 to about 0.2 deciliter per gram. These characteristics substantially improve the solubility of the poly(arylene ether) in the curable composition and allow the curable composition to be formed and used at or near room temperature. Composites formed by the process and circuit boards including the composites are also described.
